+Summary: More anonymous helper classes than needed are created
+
+Consider
+
+class X {
+	delegate void D ();
+	static void Main ()
+	{
+		bool b = false;
+		bool bb = false;
+		D d = delegate {
+			b = true;
+		};
+
+		D dd = delegate {
+			b = true;
+			bb = true;
+		};
+		d ();
+		dd ();
+	}
+}
+
+We create
+
+.class nested assembly auto ansi '<>AnonHelp<0>'
+and
+.class nested assembly auto ansi '<>AnonHelp<1>'
+
+creating two helper objects in the method. However, Microsoft only creates
+one. This increases performance by reducing the number of dereferences.
